KNOB ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 323,393, dated August4, 1885.

(ModclJ f0 allwhom it may concern:

Be it known that I, CHARLES W. BULLARD, acitizen of the United States,and a resident of Chicago, in the county of Cook and State of Illinois,have invented certain new and useful Improvements in Knob Attachments;and I do hereby declare the following to be a full, clear, and exactdescription of the same, ref ercnce being had to the accompanyingdrawings, forming a part of this specification.

This invention relates to improvements in attaching to their spindlesthat class of knobs or handles employed to operate door-looks orspring-latches; and the present improvement has for its objects, first,to provide a strong, simple, and efficient means for detachably securingthe rosette or knob to the sleeve by which it is attached to the door;second, to atford means to admit ot' the adjustment of the rosette ordoor-knob upon its combined rose and escutcheon plate, so as to permitof the vertical adj ust-ment of said rosette or knob to suit diii'ercntsizes of locks or the varying distances between the key-hole and thespindlehole of different looks. I attain such objects by theconstruction and arrangement of parts illustrated in the accompanyingdrawings, in Which- Figure 1 is a vertical section through the knob orrosette and the combined rose and escutcheon plate, illustrating myimprovement; Fig. 2, a front elevation of the com bincd rose andescutcheon plate; Fig. 3, a de tail rear elevation of such plate and theattaching parts of the rosette or knob; Fig. el, a rear elevation of theknob or rosette and its attachingslecrc, showing the mode of connectingthe same together; Fig. 5, a detail perspective view of theattaching-sleeve of the knob or rosette; Fig. 6, a similar View of theshank of said knob or rosette; Fig. 7, a de tail rear elevation of theescutcheon-plate, 810., illustrating a modified form of attaching partsof the knob or rosette, and Fig. 8 a horizontal section of the same,illustrating a modi fication of the mode of connection between 1110rosette-shank and its attaching'sleeve.

Similar letters of reference indicate like parts in the several views.

Referring to the drawings, Arepresents the knob or rosette, preferablyof metal, having a shank, A, that passes through a sleeve, B,

by which the knob is attached to the door or the escut-cheon plate ofthe same, as the case may be. In the present invention it is preferredto make the attachment to the escutcheon-plate, for purposes hereinafterstated.

The shank A and sleeve B are detachabl y connected together int-hefollowing manner: a is a radial or outwardly-projecting lug at the innerend of the shank A, which, when such shank is inserted into the sleeveB, passes along the groove or passage bin the inner periphery of thesleeve until the circular recess 12 atthe end of such sleeve is reached,when said lug is free to rotate, and thus permit of the turning of theshank A and its rosette A. It Will be seen that any movement of the luga. in the recess 1) past the groove b will lock the shank A and sleeve Btogether. In putting the parts together the shank A, after beinginserted in the sleeve B, will be turned half around, so as to bring thelug a diametrically opposite the groove 1 before the lockspindle C isinserted in its squared receivinghole a in the rosette-shank A, thepurpose being to permitthe usual rotation of the lockspindle to takeplace without bringing the locking parts above described into adisengaging position.

\Vhile the above is my preferred mode of securing the rosette-shank tothe attachingsleeve, still I do not limit my invention to the precisearrangement shown, as the arrangement of parts can be reversed, so as toattain like results, to wit: by forming thelug (4 upon the sleeve B, andthe groove 7) and recess 7) upon the rosette'shank A, as indicated inFig. 8.

To permit of a vertical adjustment of the knob or rosette upon thecombined rose and escutcheon plate D in relation to the-keyhole E, so asto suit different sizes and styles of locks in which the distancebetween the keyhole and the lock-spindle vary more or less, I employ thefollowing means: I) are a pair of beaded posts or screws in the back orrear face of the attaching-sleeve B of the rosette A. These posts areintended to pass through elongated holes or slots (1 in therose-escutcheon plate D, and by means of their heads secure the sleeveto said plate, the holes or slots be ing of an elongated form to permitof the above-mentioned adjustment of the knob or While I prefer to usefixed posts 1) upon the sleeve B to engage back of the plate D, bypassing through an enlargement, d", of the holes or slots d at theirtop, as shown, yet it is evident that such enlargement can be dispensedwith and other means substitutedsuch, for instance, as screwing suchposts into the sleeve from the back of the escutcheonplate. It is alsoevident that the elongated slots could be formed in the sleeve B withthe posts 1) arranged upon the escutcheon-plate 'and similar resultsattained; and, again, the

sleeve B may be provided with a squared shank, b, by which it can beguided in the elongated spindle-slot d, the said shank b being held inplace by a confining-plate, D, scoured to it by screws from the back ofthe escutcheonplate D, as indicated. Figs. 7 and 8.

Having thus fully described my said invention, what I claim, and desireto secure by Letters Patent, is-

1. The combination, with the combined rose and escutcheon plate D, ofthe attaching sleeve B. adjustably secured thereto, and the shank A ofthe doorknob or rosette, the one being I provided with a groove, 1), anda circular recess, b, and the other with alng, a, essentially as setforth.

2. The combination, with the combined rose and escutcheon plate D, ofthe attaching-sleeve B, adj ustably secured thereto, and provided with agroove or passage, 1), and a circular recess, b, at its rear end, andthe knob-shank A, provided with a projecting lug, a, at its end,essentially as set forth.

3. The combined rose and escutcheon plate D for door-locks, providedwith an elongated slot to permit of an adjustment on the lockspindle, incombination with the attachingsleeve B of the knob or rosette, andmeans, substantially as herein described, for adjustably attaching saidsleeve to the plate D, essentially as set forth. I

4. The combination, with the door knob or rosette and theattaching=sleeve B, provided with screws or headed posts W, of the roseand escutcheon plate D, having elongated slots (1 d and d, substantiallyas and for the purpose set forth.

5. The combination, with the door knob or rosette, and theattachingsleeve B, having screws or headed posts N, of the rose andescutcheon plate D, provided with elongated guide-slots d d, havingenlargements (Z and an elongated spindle-slot, d, essentially as and forthe purpose set forth.

In testimony whereof witness my hand this 4th day of February, 1885.
